Using 10W40 instead of SAE 30 in your lawn mower is not recommended unless specified by the manufacturer. SAE 30 is a single-viscosity oil ideal for warmer temperatures, while 10W40 is a multi-viscosity option that works in varying temperatures but may not be suitable for all engines. To avoid potential engine damage or performance issues, check your mower's manual for the manufacturer’s oil recommendation. If in doubt, sticking with SAE 30 for a lawn mower is generally a safer choice.
